cardiovascular disease, strokes, diabetes, there is an even association between gum disease and still births or low birth rate. so, it's a broader picture. >> so what you just described, is that justification for the government to step in and say, in the spirit of prevention, we need to help these kids learn good health habits? >> i think it is a very strong argument. if we're thinking about the long-term health of these children, especially as they become adults, something very simple as brushing one's teeth during daycare is really a very simple measure that will have long-lasting health benefits. >> there are certainly many physicians and otherwise that say you brush at home, why not brush also after every meal. i know i taught my children to do that when they were able to do so. for those parents who say, wait a minute, the spreading of germs -- come on, daycare centers can be incubator for germs. >> in all daycare centers there's hand washing. the child will have a new toothbrush. they'll brush themselves.
